A Passive Method of Detecting Targets Moving in Water

Abstract

A new passive method of preserving a water line verge based on detecting pressure oscillations in a field of the inhomogeneous pressure wave that arises in the streamlining of a body moving in water is considered. A feature of a wave, understood as a zone of local pressures, is the fact that it is sharply limited in space together with the body, which makes it possible to clearly monitor the zone of pressure variations.
